Unable to build Ogre

[le_shatai]

Hi

I am unable to compile ogre.
I have downloaded the CVS version 1.4-3, as it was not possible to download
a src package from sourceforge. Seems to be broken.

Anyway, when compiling ogre, I get this error:

Code: Select all

/usr/bin/ld: final link failed: Bad value

So what is the problem?
I try to compile it on this system:

Code: Select all

Intel Core2Duo E6400
Nvidia GF-7600GT
ArchLinux - 64Bit
gcc-4.2

with this configuration:

Code: Select all

../configure --prefix=/opt/ogre --disable-cg --with-platform=GLX

So what's wrong, and how do I get it compiled?

Tnx

Does noone has any idea, what can I make to get it compiled? maybe someone
from the ogre development team, or is a 64Bit-compile not possible; but the
error does not look that way.

Search please: http://www.ogre3d.org/phpBB2/viewtopic. ... light=fpic

I avoid 64-bit personally (don't need it, and too many driver hassles), but Ogre has been built on 64-bit machines. But it looks like there might be an issue with gcc 4.2 and amd64.

Time ago I have an amd64 and builded it there, I barely remember having 1 time such a problem, but in fact dont remember how I solve it, thought what I find in a search I put it here:

http://www.ogre3d.org/phpBB2/viewtopic. ... 073#234073

Perhaps the references there can help you out.

Thanks for the hints. I will see if I can find a work around to fix this.
If I can solve this problem, I will post the solution.

I am on Ubuntu 64 bit - no problems here.

Hi

Ok, I got it compiled:
These are my settings:

Code: Select all

./configure --prefix=/opt/ogre --disable-static --enable-shared --with-platform=GLX --disable-cg --with-pic --disable-ogre-demos

This are my C[XX]FLAGS:

Code: Select all

CXXFLAGS=-fpic -fvisibility=default 
CFLAGS=-fpic -fvisibility=default 

Pay attention that I did -fpic not -fPIC.
The -fvisibility flag is for GLX compile, as there was this error :

Code: Select all

 relocation R_X86_64_PC32 against 'stat'... 

I had no time to check whether the build is working or not, but we will see.

Thanks for the tips, I was experiencing the same issue here. I'll see if I grasp enough of this auto* to make it do it by default on 64 bit systems.

It's strange as it only happens with these atifs things, the rest of Ogre compiles fine. I don't think there there will be any 64 bit systems with an ancient ATI card around, so it could just as well be disabled by default on such systems

Yep confirmed. If you comment out and remove the atifs from the build it builds fine. I have no idea why, because nvparse and glsupport are handled in exactly the same way in the build, and they work fine without adding any spooky build flags.

You can also install a gcc-3.x variant and then set these before running configure:

export CC=gcc-3.4
export CXX=g++-3.4

I just got svn to compile with 3.4 after I failed with 4.x.
